Material

Type 304 stainless steel is well-suited for exterior weathering locations or interior hygienic locations such as hospitals and health care, pharmaceutical plants, research laboratories and food processing facilities. Stainless steel is corrosion resistant, durable and requires very little maintenance. Karp's stainless steel access doors have a No. 4 satin finish, which is a general purpose bright finish with a visible "grain" which prevents mirror reflection.
